Hello forum!!

 

I would like to know if the cable sizing formula vary as per Industry standards. I mean, is there a particular sizing formula as per IEC standard and another formula as per IEEE standard.

Hi,

 

There is no specific formula for sizing the cable, it depends upon some factors which must be taken in to account during cable sizing such as,

 

1. Route length.

2. Environmental temperature.

3. Lay in air or buried.

4. Grouping factor.

5. Safety/ageing factor.

6. Peak starting current of load and duration.

 

May be there are many other factors which can be added by other experts.
